Abstract
It has two groups of thin partitions, which are parallel in one group and perpendicular from one group to the next, which are grooved and nested to define square cavities. Support points are made in the walls of the cavity to hold in place the fuel elements. In each group, a thin partition is constituted by two superimposed sheets. The height of the first sheet is equal to double the height of the second sheet. A first sheet is positioned above the second sheet in one of the groups and below the latter in the other group. Each second sheet is nested into the first sheet of the other group.
